As productive use of renewable energy (PURE) markets continue to expand across sub-Saharan Africa, a new challenge is emerging: what happens to the batteries powering electric mobility, irrigation, cooling, agro-processing and other productive energy applications when they reach the end of their first life?
Overview
This report examines how second-life batteries can help address this challenge by retaining valuable energy storage capacity within the system rather than allowing it to be lost through premature disposal. Drawing on insights from seven companies supported through PREO, Energy Catalyst and EEP Africa, the report explores the commercial, technical and market conditions needed to unlock battery reuse and repurposing at scale.
The report argues that the next phase of energy access growth will depend not only on advances in battery technology, but on the development of the wider market infrastructure needed to support circular battery value chains. Through case studies spanning battery testing, refurbishment, manufacturing, leasing, Battery-as-a-Service models and productive use applications, it highlights how companies are building the foundations of a second-life battery ecosystem across Africa. The report identifies key barriers, including limited testing and certification systems, financing constraints, regulatory gaps and the need for stronger mechanisms to build trust in second-life products.
By examining emerging business models and practical lessons from across the sector, the report provides actionable insights for businesses, investors, policymakers and development partners seeking to strengthen circularity, reduce costs and improve the long-term sustainability of productive energy systems. It demonstrates how second-life batteries can play an important role in making energy solutions more affordable, resilient and accessible, while helping productive energy markets continue to scale sustainably.
Key themes explored in the report include:
- The growing challenge of battery end-of-life as productive energy and e-mobility markets scale.
- Why second-life batteries represent a valuable asset rather than a waste stream.
- The infrastructure needed to enable large-scale battery reuse and repurposing.
- Emerging business models and case studies from across the second-life battery value chain.
- The role of policy, finance, standards and certification in building a trusted market.
- Opportunities for second-life batteries to support more affordable, circular and resilient energy systems.
